BS 7439:1991

This standard BS 7439:1991 Method for exchange of information for the analytical assessment of shock resistance of mechanical systems is classified in these ICS categories:

• 17.160 Vibrations, shock and vibration measurements

This International Standard establishes the procedures for specifying the analytical methods which can be used to assess the shock resistance of mechanical systems (products or human subjects).

It provides a protocol for conducting and documenting a shock analysis and identifies the requirements of the protocol.

It applies to any product or human subject for which an analytical assessment of its shock resistance is required.

NOTE 1 In this International Standard, unless noted otherwise, the term “product” is used to designate an engineering artifact (for example, equipment, component, machine, vehicle or structure).

NOTE 2 Neither the parameters characterizing the shock environments of concern nor acceptable levels of performance are associated with specific numerical values in this International Standard. When evaluating the shock resistance of a specific product to specific shock environments and/or levels of performance, it is necessary that appropriate numerical values be assigned to these parameters; this International Standard only establishes how such an evaluation can be carried out and does not specify the numerical values that could or should be assigned in any specific instance.
